BLlND-FASTEN ER.

SPECIFICATION forming part of Letters Patent No. 453,590, dated June 2, 1891.

Application filed February 7, 1891. Serial No. 380,635. (No model.)

To aZZ whom it may concern.-

Be it known that I, HENRY O. BUSHNELL, a citizen of the United States, residing at Providence, in the State of Rhode Island, have invented a new and useful Improvement in Blind-Fasteners, of which the following is a specification.

The object of my invention is to provide a suitable device which will prevent sparrows from appropriating the fastener as a desirable place to roost, to the consequent disfigurement of the side of the building; and my invention consists in a blind-fastener provided with a keeper, which is protected by means of an upward extension or spur between. the opened blind and the side of the building, whereby the sparrows will be prevented from obtaining a proper foothold upon the keeper, as hereinafter set forth.

Figure 1 represents a side elevation of the keeper, showing an edge View of the lower portion of the blind with the building-wall in section. Figs. 2 and 3 illustrate certain modifications in the device.

In the accompanying drawings, A represents the lower portion of an opened blind; I3, the side wall of the building to which the blind is attached, and a the space between the blind and wall in which the sparrows are accustomed to roost; and in carrying out my invention I prefer to form an upward extension or spur 1) upon the fastening-keeperC, which is screwed to the wall B and engages with the hook D upon the blind, the said extension servingto prcventthe sparrows from obtaining a roosting foothold upon the keeper 0. This extension. can be made in a variety of forms, and can be provided at bothedges of the catch, as shown in Fig. 2, in order that the keeper may be more conveniently adj usted in position than would be the case when a full turn of the screw 0 is required, as in the keeper shown in Fig. 1, whereas in the case of the keeper shown in Fig. 2 but one-half of aturn will be required to bring one of the extensions Z) uppermost from the greatest extreme.

In Fig. 3 the keeperGis shown asadapted to a horizontal position, and is provided with the opposite upward extensions 1) b, which serve to prevent the sparrows from roosting upon either arm 01 of the keeper, and the said upward extensions may be made in any desired form and in any suitable number for the purpose set forth.

I claim as my invention- 1. A blind-fastening keeper provided with an upward extension or spur, substantially as and for the purpose specified.

2. The combination, with the blind and its fastening-hook, of the keeper provided with an upward projection or spur adapted to prevent sparrows from roosting upon the keeper, substantially as described.

HENRY C. BUSHNELL.
